| crystal structure of bacteriophage ϕnit1 zinc peptidase pghp that hydrolyzes γ-glutamyl linkage of bacterial poly-γ-glutamate. | poly-γ-glutamate hydrolase p (pghp) of bacillus subtilis bacteriophage φnit1 hydrolyzes the γ-glutamyl peptide linkage of extracellular poly-γ-glutamate produced by bacilli, which facilitates infection and propagation of phage progenies. crystal structure of pghp was determined at a resolution of 1.9 å. structure of pghp was elucidated as a globular protein with an open α/β mixed core structure and a seven-stranded parallel/anti-parallel β-sheet. the β-sheet contained a core four-stranded parall ... | 2011 | 22105902 |
